UNITED STATES HAROLD W. DEARING, OF NEW YORK, N. Y,

PRESERVE-JAR OPENER.

Application filed May 17, 1920.

To all whom it may concern:

Be it known that I, HAROLD W. DEARING, a citizen or the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Preservelar Gpencrs, of which the following is a full, clear, and exact description.

The frequent difiiculty met with in opening a glass top preserve jar is a most familiar and vexatious experience with all housekeepers. Tie partial vacuum within the jarnot only resists its removal from its rubber seat, but it almost inevitably happens that more or less of the syrupy contents of the jar coat the rubber bands and drying tend to cement the glass cover down, rendering it still more diiiicult to remove it.

The method usually followed in such cases is to pry up the cover with a knife or any sharp tool that may come to hand, but this is likely to injure either the jar or the tool, often resultin in the chipping or breaking of the glass, impairment of the rubber band or wounding of the person endeavoring to remove the cap or cover. To avoid this many appliances have been devised for raising such caps, but few have ever made their appearance on the market, and none, so far as I am aware, have ever met the requirements of practical use, or been of such a character that they could be manufactured and sold at a cost which the conditions of use of such appliances require.

1. have sought to overcome these objections and to produce a simple, cheap and highly useful and practical device for this purpose, which shall be of such nature that its application and operation is obvious to even the most unskilled person, and which, while infallible so far as its results are concerned, is incapable of injuring the jar, the rubber band orthe one who may use it.

For this purpose I employ two relatively light, rigid and preferably metal bars pivoted end to end by a pin which serves also as the bearing for a metal disk with a suit ably beveled edge which lies between the two bars. At a short distance from the pivotal pin the ends of a wire are secured to the bars to form a loop of sufiicient dimensions to readily pass over the glass cap of any of the ordinary and well known jars of this character which are now in use. This is the complete ClQVlCG, In usmg it the loop is passed over and around the glass cap and Specification of Letters Patent.

band and the under edge of the cap. This raises the cap, permits air to enter the jar and so makes the removal of the cap a matter of no diiiiculty.

This device is illustrated in the accompanying drawings, in which:

Figure 1 is a perspective view of the top of a preserve jar, showing the manner of applying or using my improved opener.

Fig. 2 is a sectional view showing the re lations of the parts at the moment of applying the device.

' Fig. 3 is a similar view showing the relations of the same parts at the moment when the bars or handles have been moved toward one another and the disk forced home between the cap and the underlying rubber rmg.

Fig. l is a plan view showing a modification in the form of the bars or handles.

The two bars or handles which may be of iron or any other suitable rigid material are indicated by the numerals 1 and 2. They are pivoted together by a pin 3 which passes through them near their ends. This pin also serves as a bearing for a metal disk 4, which is free to turn on the pin and which is between the two bars 1 and 2.

Secured to the bars in any convenient manner, at points relatively near their ends is a wire loop 5 of such length that when the two bars are in substantial alinement, its diameter will permit it to pass down over and around the glass cap of any ordinary preserve jar, as shown in Fig. 1.

In using this device the bars are brought in line, the loop passed down over the glass cap, as shown in Fig. 1, and the edge of the disk, which as shown is beveled from the lower side upwardly, is broughtimmediately under the edge of the glass cap, the lower fiat side on the usual rubber seat or ring 6.

The bars are then turned on their pivotal connection which has the effect of reducing the diameter of the loop and thus forcing the disk in between the cap and the rubber ring. As soon as the cap, in this way, is slightly raised the air enters the jar and the further raising of the cap is unopposed.

lVhile the parts of the device may be greatly varied in form, dhnensions and in the materials used, by the manufacture,

without departure from the spirit of the invention, certain peculiarities which I have herein illustrated may be called attention to as conducing materially to the efiicacy and value of the implement. The disk, for eX- ample, should have a single and upwardly inclined beveled edge, as it is not then likely to injure the rubber ring or gasket. The ends of the bars or handles also, as shown in Fig. 4, are preferably rounded, so that, when turned toward each other, they will encounter the rubber ring or the top edge of the jar and thus limit the extent to which the edge of the disk may enter between the cap and the ring. This not only prevents injury to the. disk but possibility of fracturing the glass of the jar. Other features herein shown will be recognized as advantageous without further description. I

What I claim as my invention is:

1. A preserve jar opener comprising in combination a pair of bars pivoted end to the pivot pin.

sides of the pivotal point to form a loop that may be passed down and around the cap. 7

2. The combination with two metal bars or handles of a pivot pin uniting their ends, a metal disk with an upwardly inclined beveled edge mounted between'the bars on the pivot pin, and a wire loop the ends of which are connected to the bars on opposite sides of 3.The combination with two metal bars or handles with rounded ends, .a pivot pin uniting their rounded ends, a metal disk carried by the pivot pin and a wire loop the ends of which are connected to the bars on opposite sides oi the pivot pin. 7

In testimony whereof I hereto aflix my signature.
